This is how my project structure looks like
namespace Factory.Model
{
Public Partial class FactoryEntities:Dbcontext{
public FactoryEntities()
:base("name="factoryentities")
{
this.configuration.lazyloading = false;
}
public DbSet<Factory> Factories{ get; set; }
public DbSet<FactoryCoverage> FactoryCoverages { get; set; }
}
}
This is the Business logic
Here's how I use the Entities
namespace Factory.Business
{
partial class Class1
{
Factory.Model _factory;
private LoadMethod(long id)
{
using(var fnt = new FactoryEntities())
{
_factory = fnt.factories.include(.)....
}
}
Once all the items and entities are loading into the _factory object, some Winforms are called
Form1 f1=new Form1(_factory)
BindingSourcef1.DataSource = _factory
Form f1 has some textboxes bound to the BindingSourcef1
this.textbox1.databindings.add("EditValue",this.BindingSourcef1, "Address.City", true));
Question: How do I track changes to this textboxes. Something like, when a user changes a textbox value, notify the user with an asterisk(*) that there are changes made to the form?
I was able to make this work by handling textbox edit value event.
Is there an alternative to this?Handling it at Bindingsource level would be ideal.
I want to track the change immediately to notify the user that there is an edit .No button click is involved yet. I could easily track it on SaveChanges. context.Savechanges(); or context.ObjectStateManager. Also, Currentitemchanged dosen't seem to be
executed. So the property should be marked as edited.
